Is it possible to create a new CCS project using starterWare example design?

Hi there,
I have now managed to get the example design building. And it was but added the nand.lib, etc libraries..
Could you please let me know what is that needed? Is there a way to write/read to nand flash without this *.lib files?

Mitesh

Yes, it is possible to create a new project in CCS. As well as, if you are using the starterware project, you can directly import the existing project and build it.

The following are the steps to import and re-build the project.

1. Open CCS --> Project --> Open existing CCS Eclipse project --> select search directory --> < give the path where the *.ccsproject lies. i.e, ~\ti\OMAPL138_StarterWare_1_10_04_01\build\armv5\cgt_ccs\omapl138\lcdkOMAPL138\nand > --> click finish

2. Rebuild. This will build successfully by default.

3. If it throws error, right click on project properties --> resources --> linked resources--> path variables. Check whether all the paths to the sources are appropriate / valid and there is no conflict in the location.

4. Please post the screenshot of your project properties of this "NAND" project of OMAPL138 starterware. 

 

Thanks Guys. but if u see my second post. I did at the end manage to get the example design rebuild. However, I want to build without the need of the lib files viz., nand.lib, system_config.lib, platform.lib, etc. is it possible? n what is the *.lib files ?

Hi,

May be, you could check the project and build handbook for CCS as below which would help you better in importing, adding or linking source files/folders to the project workspace:

Thanks both Shankari and Titus.
Yup, it now make sense.
Yes, I am modifying the NAND read write example. (StarterWare Example)

As Titus suggested, I have removed all the links I created to *.lib files and added the actual *.c files to the project. And one problem in doing so was the files inside the platform is also named same as the drivers ;) I have changed the file name and all seems to work now. Thanks for the support.

One final question, what's your recommendation? In an actual design that consists of more than one peripheral used, would you combine all the platform depended files (pinmux, init) in one common config file or use the *.lib as in the example ?

In general, the example design uses *.lib files and the example I have modified uses 1 common file for the config (Combined all the source files nand.c,emifa.c,etc) is any method better than the other?

It depends upon your software design. For modularity purposes, library files are created. No problem in combining the source files. Actually in starterware, it is organised in such a way to demonstrate one example for each periheral etc,.

 

 

Shankari,

It doesn't affect performance or the code length in either of the cases right? Could you also send me a link which explains how to convert code into libraries? Thanks Shankari.

Mitesh

Mitesh,

Codes are not converted but "built" as libraries .
Go to CCS help menu and type "Library-build process"; You will get lot of documentations.

As well, you can refer the build configurations of "NANDlib" or "usblib" sample projects enclosed in the starterware.

Okay thanks. will check.
I have one more question, I have created a simple design in which the DSP received data from a PC as an UDP packet and I then want to write that data to NAND flash.
So I have created a task which would write data to NAND and is pend on a Semaphore. I would like to post the semaphore, once I receive the UDP packet in the NDK. I have added the post semaphore function inside the helloworld example design, that is, in the dtask_udp_echo hook function. Is this right way of doing it? ta

Hi Mitesh,

I would recommend you to open up a new question.

Appending one or more questions repeatedly on the closed posts will seek very less attention compared to the new ones.

 

Thanks for understanding.
